GRAPPLE.

SPECIFICATION forming part of Letters Patent No. 635,146, dated October 17, 1899.

Application filed May 24, l899. Serial No. 7181076. (No model.)

Norway, and WILLIAM ADoLF OLsEN, a citi- Zen of the United States of America, and both residents of New York city, county and State of New York, have invented certain new and useful Improvements in Grapples, of which the following is a specification.

Our invention consists of improvements in grappling tongs and scoops for use on der ricks for grappling and hoisting stones, earth, and other heavy bodies, as hereinafter described, reference being made to the accompanying drawings, in which- Figure l is an elevation of a grapplingtongs suspended from the boom of a derrick in accordance with our invention. Fig. 2 is an elevation of the tongs in a view at right anglesto the view of Fig. 1 and enlarged. Fig. 3 is a detail showing a detachable pad for application of the points of the tongs for handling dressed stones without injury.

A pair of grappling-jaws a, having shanks b, are crossed and pivoted together at c in the usual manner. One of the Shanks has a socket d at the upper end, in which a pole e. is detachably secured as a means of controlling the tongs from a scow when grappling objects under water. The shanks of the jaws are suspended by chains f, connected to them at g above the pivot c from a pulleyblock h, through which the hoisting-rope t' works to close the tongs and lift the weight, said rope being suspended from the upper end of the boom 7' at c and arranged over a pulley l, also located at the upper end of the boom, from which said rope extends downward to the platform for application of the power in any approved way, but is here shown as fastened to a cleatmon the post 'n'. This arrangement of means for grappling and hoisting the weight is, however, practically the same as in common use and is not claimed by us. v

The essential part of ourinvention is in thc means of opening the jaws to discharge the. weight, as follows: -To each jaw, interthe platform for being manipulated; but itis here shown as fastened to a cleat u'. It is,

however, to be let free when the jaws descend to take a load, andwhen rope t is drawn for raising the load rope t will also be drawn, but only to take up the slack; but

to be injured by the points w, said grips being provided Awith sockets for conveniently attaching to the points of the jaws, and they are pivoted to the sockets at y for the requisite articulation for the proper application of the faces of the grips to the surfaces of the stones.

We are aware that grapples specially made for the use of pad-grips permanently pivoted to the jaws have been used, said jaws being only useful with the grip-pads, as shown in the patent to Moore, No. 354,431, and we do not claim jointed pad-grips broadly, our invention being jaws adapted for general use and convertible at will for pad-grips.

What we claim as our invention is- 1. The combination with grappling-jaws a, shanks of said jaws b, and the jaw-closing and hoisting chainsfand rope t', said jaws being pivoted together at c, of the jaw-opening ropes n, attached to the jaws ct below said pivot c, and extended over pulleys p at the upper extremities of the Shanks Z1, thence Over the pulleys on pivot c, and thence t0 the Signed by us at New York, N.
